Description

Technical Field

[0001] The utility model relates to the field of high-precision drilling devices, and specifically relates to a high-precision drilling device for the production of low shaft rings. Background Technique

[0002] The low shaft ring is a structural element used for axial positioning in mechanical design. The main function of the low shaft ring is to maintain the relative position of parts, prevent relative displacement of components during operation, thereby protecting the normal operation of equipment and mechanical components. The design and processing of the low shaft ring are crucial for ensuring the normal operation and optimizing the performance of mechanical equipment. In different application scenarios, the low shaft ring can select different materials and designs according to needs to adapt to specific working environments and performance requirements. Before the low shaft ring reaches its use state, it often needs to be drilled to meet the use requirements.

[0003] The application of drilling the low shaft ring is very extensive. It can be used for installing bearings, sealing elements, connecting parts or other mechanical components. The technical characteristics of drilling the low shaft ring include high requirements for precision because these holes usually fit tightly with other mechanical components, and depending on the different shaft materials, special cooling fluids may be required during the drilling process to improve processing efficiency and prevent tool damage.

[0004] The existing drilling devices usually need to fix the low shaft ring when drilling it. The low shaft ring is manually placed in its fixture, and then drilled by the drilling device. However, this method has low work efficiency, and it is rather troublesome to manually take it out after drilling. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a high-precision drilling device for the production of low shaft rings to solve the technical problems of low work efficiency of the existing drilling devices and the inability to clean metal iron filings.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-precision drilling device for the production of low shaft rings, including an operation platform. A clamping workbench is installed on one side of the operation platform. A cleaning component is arranged at one end of the operation platform. A drilling workbench is installed on the other side of the operation platform. Two groups of rotating shafts are installed inside the operation platform. A conveyor belt is sleeved on the outer walls of the two groups of rotating shafts. A driving motor is arranged at the end of one group of rotating shafts. Clamping hydraulic rods are installed on one side of both the clamping workbench and the drilling workbench. A clamping component is installed at the output end of the clamping hydraulic rod on one side of the clamping workbench. A drilling chuck is fixed at the output end of the clamping hydraulic rod on one side of the drilling workbench. A drilling hydraulic rod is installed at one end of the top of the drilling workbench. A drilling component is fixed at one end of the drilling hydraulic rod.

[0007] By adopting the above technical solution, the problem of low working efficiency of the existing drilling device is solved. The low shaft ring is placed above the conveyor belt for feeding. After drilling, it does not need to be manually removed. When the conveyor belt conveys the low shaft ring to the middle, the clamping hydraulic rod drives the drilling clamp block and the fixed clamp block to move forward at the same time. The centering clamping plates on both sides of the fixed clamp block can move closer inward, so as to correct the slightly offset low shaft ring, making the low shaft ring located at the center of the fixed clamp block and the drilling clamp block, facilitating drilling on it, and then drilling it through the drilling assembly.

[0008] The present utility model is further configured such that the clamping assembly includes a fixed clamp block fixed to the end of the clamping hydraulic rod, and a sliding convex block is movably installed inside the fixed clamp block. An induction block is fixed to the end of the sliding convex block, and pull rods are fixed to both ends of the induction block. The centering clamping plates are installed on both sides of the fixed clamp block through rotation holes.

[0009] By adopting the above technical solution, when the low shaft ring contacts the induction block, the centering clamping plates are driven to rotate, which will add a clamping and limiting effect to the low shaft ring, reduce the alignment time of the low shaft ring, and reduce the time used in the drilling process.

[0010] The present utility model is further configured such that the cleaning assembly includes a reciprocating lead screw movably installed inside the operation platform, and a cleaning block is sleeved on the outer wall of the reciprocating lead screw. A transmission assembly is provided at the end of the reciprocating lead screw, and the reciprocating lead screw is connected to a group of the rotating shafts through the transmission assembly.

[0011] By adopting the above technical solution, the cleaning block can reciprocate driven by the lead screw, and the debris on the conveyor belt can be cleaned to avoid the problem of damaging the surface of the low shaft ring in the later stage.

[0012] The present utility model is further configured such that a transmission inner cavity is opened at the end of the centering clamping plate, and sliding inner grooves are opened on both sides of the inner wall of the transmission inner cavity. A limiting ring is fixed to the end of the inner cavity of the hydraulic rod, and the outer wall of the limiting ring fits with the inner wall of the sliding inner groove.

[0013] By adopting the above technical solution, through the provided sliding inner grooves, the centering sliders slide inside them, so that the centering clamping plates achieve the centering effect. The limiting ring fixed to the end of the inner cavity of the hydraulic rod can play a limiting role on the sliding convex block at one end of the induction block to prevent it from falling off.

[0014] The present utility model is further configured such that a limiting rod is fixed inside the operation platform on one side of the reciprocating lead screw, and the limiting rod passes through the cleaning block, and a cleaning brush is fixed to one side of the cleaning block.

[0015] By adopting the above technical solution, during the operation of the cleaning block, there is a limiting effect to prevent the cleaning block from flipping, so that the metal iron filings cannot be cleaned. The setting of the cleaning brush can make it fit more closely with the conveyor belt, strengthening the cleaning effect of the metal iron filings on the conveyor belt.

[0016] The present utility model is further configured such that a hydraulic rod inner cavity is provided inside the fixed clamping block, and a clamping spring is fixed to the inner wall of the hydraulic rod inner cavity, and the clamping spring is fixedly connected to the sliding convex block.

[0017] By adopting the above technical solution, by squeezing the clamping spring through the sliding convex block, the induction block can be telescoped. After the drilling is completed, the induction block can be ejected by the reset of the spring for the next drilling process.

[0018] The present utility model is further configured such that the transmission assembly includes a driven gear fixed to the end of the reciprocating lead screw, one end of a set of rotating shafts is fixed with a driving gear, and the driving gear is meshed with the driven gear, and the diameter of the driving gear is larger than that of the driven gear.

[0019] By adopting the above technical solution, through the linkage of the driving gear and the driven gear, the reciprocating lead screw and the conveyor belt rotate synchronously, avoiding the situation that the surface of the conveyor belt is not cleaned. The larger diameter of the driving gear than that of the driven gear increases the reciprocating frequency of the cleaning block, strengthening the cleaning effect on the surface of the conveyor belt.

[0020] The present utility model is further configured such that a reserved hole is provided inside the drilling clamping block.

[0021] By adopting the above technical solution, it is convenient for the drilling assembly to drill one side of the low shaft collar.

[0022] In summary, the present utility model mainly has the following beneficial effects:

[0023] 1. By setting the reciprocating lead screw, cleaning block, cleaning brush, fixed clamping block, rotating rod, clamping spring, induction block and centering clamp plate, the present utility model solves the problem of low working efficiency of the existing drilling device. The low shaft collar is placed above the conveyor belt for feeding, and it does not need to be manually removed after drilling. When the conveyor belt conveys the low shaft collar to the middle, the drilling clamping block and the fixed clamping block are simultaneously driven forward by the clamping hydraulic rod, and the centering clamp plates on both sides of the fixed clamping block can move closer inward, thereby correcting the slightly offset low shaft collar so that the low shaft collar is located at the center of the fixed clamping block and the drilling clamping block, facilitating drilling on it, and then drilling is carried out on it by the drilling assembly.

[0024] 2. The utility model realizes the purpose of cleaning the outer wall of the conveyor belt by setting a reciprocating lead screw, a cleaning block and a transmission component. The transmission component drives the reciprocating lead screw to rotate, so that the cleaning block can move reciprocally, thereby cleaning the debris generated during the drilling process, avoiding the residue of metal iron filings on the top of the conveyor belt, and preventing damage to the surface of the low shaft collar in the later stage.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0035] Next, the embodiments of the present utility model will be described according to its overall structure.

[0036] A high-precision drilling device for low collar production, as Figure 1 - Figure 8 shown, includes an operation platform 1, a clamping workbench 2 is installed on one side of the operation platform 1, a cleaning component is arranged at one end of the operation platform 1, a drilling workbench 3 is installed on the other side of the operation platform 1, two groups of rotating shafts 8 are installed inside the operation platform 1, a conveyor belt 9 is sleeved on the outer walls of the two groups of rotating shafts 8, a driving motor 81 is arranged at the end of one group of rotating shafts 8, clamping hydraulic rods 10 are installed on one side of both the clamping workbench 2 and the drilling workbench 3, a clamping component is installed at the output end of the clamping hydraulic rod 10 on one side of the clamping workbench 2, a drilling clamp block 21 is fixed at the output end of the clamping hydraulic rod 10 on one side of the drilling workbench 3, a drilling hydraulic rod 23 is installed at one end of the top of the drilling workbench 3, and a drilling component 11 is fixed at one end of the drilling hydraulic rod 23.

[0037] Please refer to Figure 3 and Figure 4 . The clamping component includes a fixed clamp block 12 fixed at the end of the clamping hydraulic rod 10, and a sliding convex block 14 is movably installed inside the fixed clamp block 12. An induction block 17 is fixed at the end of the sliding convex block 14, and pull rods 13 are fixed at both ends of the induction block 17. Poly-position clamping plates 18 are installed on both sides of the fixed clamp block 12 through rotation holes 19. By contacting the low collar with the induction block 17, the poly-position clamping plates 18 are driven to rotate, which can play a role in clamping and limiting the low collar, reduce the alignment time of the low collar, and reduce the time used in the drilling process.

[0038] Please refer to Figure 1 and Figure 5 . The cleaning component includes a reciprocating lead screw 6 movably installed inside the operation platform 1, a cleaning block 7 is sleeved on the outer wall of the reciprocating lead screw 6, a transmission component is arranged at the end of the reciprocating lead screw 6, and the reciprocating lead screw 6 is connected to one group of rotating shafts 8 through the transmission component. By driving the cleaning block 7 with the lead screw, it can reciprocate to clean the debris on the conveyor belt 9 and avoid the problem of damaging the surface of the low collar in the later stage.

[0039] Please refer to Figure 4 and Figure 6 . A transmission inner cavity 24 is opened at the end of the poly-position clamping plate 18, and sliding inner grooves 20 are opened on both sides of the inner wall of the transmission inner cavity 24. A limiting ring 151 is fixed at the end of the inner cavity 15 of the hydraulic rod, and the outer wall of the limiting ring 151 fits with the inner wall of the sliding inner groove 20. By providing the sliding inner groove 20, the poly-position sliding block 141 slides inside it, so as to make the poly-position clamping plate 18 achieve the poly-position effect. The limiting ring 151 fixed at the end of the inner cavity 15 of the hydraulic rod can play a limiting role on the sliding convex block 14 at one end of the induction block 17 to prevent it from falling off.

[0040] Please refer toFigure 1 and Figure 5 Inside the operation platform 1, a limiting rod 72 is fixed on one side of the reciprocating lead screw 6, and the limiting rod 72 passes through the cleaning block 7. A cleaning brush 71 is fixed on one side of the cleaning block 7. The limiting rod 72 passing through the cleaning block 7 has a limiting effect when the cleaning block 7 works, preventing the cleaning block 7 from flipping and being unable to clean the metal iron filings. The setting of the cleaning brush 71 can make it fit more closely with the conveyor belt 9, strengthening the cleaning effect of the metal iron filings on the conveyor belt 9.

[0041] Please refer to Figure 4 Inside the fixed clamping block 12, a hydraulic rod inner cavity 15 is opened, and a clamping spring 16 is fixed on the inner wall of the hydraulic rod inner cavity 15. The clamping spring 16 is fixedly connected with the sliding convex block 14. By squeezing the clamping spring 16 through the sliding convex block 14, the induction block 17 can be telescoped. After drilling, the induction block 17 can be ejected by the reset of the clamping spring 16 for the next drilling process.

[0042] Please refer to Figure 1 The transmission component includes a driven gear 5 fixed at the end of the reciprocating lead screw 6. One end of a group of rotating shafts 8 is fixed with a driving gear 4, and the driving gear 4 is meshed with the driven gear 5. The diameter of the driving gear 4 is larger than that of the driven gear 5. Through the linkage of the driving gear 4 and the driven gear 5, the reciprocating lead screw 6 and the conveyor belt 9 rotate synchronously, avoiding the situation that the surface of the conveyor belt 9 is not cleaned. The larger diameter of the driving gear 4 than that of the driven gear 5 increases the reciprocating frequency of the cleaning block 7, strengthening the cleaning effect on the surface of the conveyor belt 9.

[0043] Please refer to Figure 1 A reserved hole 22 is opened inside the drilling clamping block 21, facilitating the drilling of the low shaft ring side by the drilling component 11.

[0044] The working principle of the present utility model is as follows: After evenly placing the low shaft rings on the conveyor belt 9, start the driving motor 81 to drive the conveyor belt 9. After the low shaft rings reach the designated position, the conveyor belt 9 stops rotating. The clamping hydraulic rod 10 pushes the fixed clamping block 12 and the drilling clamping block 21 forward. When the induction block 17 in the fixed clamping block 12 comes into contact with the low shaft ring, the induction block 17 will slide into the interior of the fixed clamping block 12 due to the extrusion of the low shaft ring, and through the centering slider 141 at one end of the pull rod 13, the centering clamping plates 18 on both sides will rotate inwards, pushing the low shaft ring to move between the fixed clamping block 12 and the drilling clamping block 21, accelerating the alignment of the low shaft rings. After the low shaft rings are aligned, then the drilling hydraulic rod 23 pushes the drilling assembly 11 forward to perform the drilling process. After the drilling is completed, the clamping hydraulic rod 10 and the drilling hydraulic rod 23 drive the clamping assembly and the drilling assembly 11 to reset. The conveyor belt 9 rotates to take away the low shaft rings, and the conveyor belt 9 drives the metal fragments to move towards one side of the operation platform 1. The cleaning brush 71 driven by the transmission assembly cleans the metal fragments to prevent them from contacting the conveyor belt 9. The cleaning brush 71 is fixed on the cleaning block 7, and through holes are provided on the cleaning block 7, and the cleaning block 7 is sleeved on the limiting rod 72 between the operation platforms 1 through the through holes.
